l SANITARY msn-WASHER.

Application led February 9, 1920. Serial No. 357,444.

T 0 all/whom t may concern: y

Be it known that I, HERMAN W. HIGLEY, citizen of the United States, anda resident of Yonkers, in the county of Westchester and State of NewYork, have invented certain new and useful Improvements in SanitaryDish-Washers, of which the following is a specification. Y

The object of my inventionis to provide a dish washer employing both arunning stream of water and a pliant rubber scraper,

conveniently arranged to work in conjunction with one another, sothatvthe operator or user may employ eitherl the water or scraper, orboth. Thev water may be first applied, for the removal of all loosesubstances, while the scraper may be employed* during the same operationin rubbing and scraping the dried and hard particles, with the flowingwater used as an assistant.-

In this combination I provide means convenient to the operator or userfor the manipulation of both water and scraper, and both are necessaryin thev removaland cleansing of food stuffs from the utensils.

The water alone doesnot provide proper means forremoving the hard anddried particles, such as dried egg, syrups and other hard drying foodstuffs, which have. to be subjected to agitation in addition to thewater to loosen andremove the same.

In my invention I provide a nozzle attached to a flexible tube, forconveying the water, that will condense the water into ay stream of athin, uniform width andthickness under pressure. The stream, to cover aslarge a surface as possible, -isv arranged thin andwide, with means formaintaining the shape or form intoa solid flow of water about onesixty-fourth of an inch in thickness and two inches wide at the nose ofthe nozzle. The stream gradually increases in width as it leaves thenose. An object is to maintain an even force of the flow across theentire width, without spreading or separating in particles from the mainstream, keeping and maintaining the entire width of the stream or floweffective for quick and practical results. `The water is transmittedfrom the nose of the nozzle in a condensed sheet form, resembling asheet of glass in appearance, iovving uniformly the entire width andthickness.

In other similar devices of this character trouble is experienced inmaintaining a stream of suitable shape in a uniform width and thicknessacross the entire surface of the stream. means for condensing the watery,in such a manner v that an even and uniform iiow is provided. Thesecondensers are arranged in the nose of the nozzle, shaping the course ofthe water so that the stream holds together in a fiat sheet within afixed distance from the nose of the nozzle. In this manner I overcomethe disadvantages of'a loose, irregular stream, as discharged from thenose of a nozzle Without the use of condensers. In addition to thestream or water flow as outlined I employ a rubber band attachment, foruse as a scraperin removing the remaining substance the water flow doesnot wash away. Owing to'the elasticity of the rubber it will clean bothvsmooth and irregular surfaces with'equal effectiveness, and owing toitspliability may be worked into crevices and uneven surfaces withrapidity, removing all substances from the even and uneven surfacesalike, when.the scraper is used in a rubbingv or scraping movement overthe matter to be removed. ADuring the rubbing `and scraping movement thewater flow is being applied from thenose of the nozzle, the watersoftening the substance during the'rubbing operation.

The scraper forms'an important part of my invention, as other devicesdepending solely upon the water flow, hot orcold, have In my improvementI 'employ l Specification of Letters Patent. Patented 14 1920.

the -v'vater does not possess suiicient dissolv- Ving properties ltoremove the hard particles,

and therefore does not wash anything but the loose substance away.

By the addition of the scraper in connection with the water iiow, thescraper being used for removing the hard and dried particles, I overcomethe disadvantages of other similar devices, and this together with animproved stream or water flow of a uniform width and thickness,constitute the important features of my invention.

I attain these objects. by means of the mechanism illustrated in theaccompanying drawing, in Which,-

Figure 1 is a plan view showing the nozzle attached to the flexibletubing with a sheet 'of water being discharged from the nose.

Fig. 2 is the same view as No. l omitting the water stream and rubberscraper, showing the condensers on both sides.

Fig. 3 is an end view looking directly into the nose of the nozzle.

Fig. 4 is a sectional view at 'af-a Fig. 2. Fig. 5 is a side viewshowing the thickness ofthe stream of water being discharged. Similarnumerals refer to similar parts throughout the several views. f

The nozzle is composed of two parts 1 and 2, which are soldered togetherat l'the joint or seam 3, as clearly shown in Fig. 5, and correspond inshape and form with each other. The parts 1 and 2 are pressed from thinmetal, so that when joined together at the seam Sileave a water chamber4, YF ig.

4, within Ythe shell, of the shape and form of the outside of thel parts1 and 2, less the thickness as shown throughout the drawy in s.

he round shank 5 with Vthe securing bands 6, V6b Aand 6c, provide meansforattaching and securing the flexible hose for conveying the water tothe water chamber The water flow is fedv within the nozzle. from afaucet, through thellexible hose 7 to the opening in the shank 5vengaged within the hose.v n n Withthe hose connected tothe lfaucet orVwater supplyfthe water will Vfirst pass the nozzle,l where theopening4,F-ig. 3, or; lthe nose of the nozzle is arranged. The

nose v12V of thelnozzle is made rounding tov assist in regulating theflow of? the stream to the proper thickness,'which according to thatarranged is about one sixty-fourth of'V kan inchjthick, although thethickness may be varied to meet necessary requirements.

densers force the water in its flowV into a Y solid mass that holdstogether after passing from the nose of thenozzle, regulating the streamto a fixed anduniform width.V

The rubber scraper'16 having a narrow flat, scraping surface 17, withbeveled edges 18, is arranged to fit snugly and tightly over the widerportion of the nozzle, near the nose 12, where it assumes a convenientposition for use in combination with the use of the stream. The'scraperlrmay be adjusted in separate pieces tovboth sides of the body by meansof rivetsor otherwise. lhile the scraper is made with a narrow Hatsurface 17, and beveled sides, as a more prac.- tical form to beemployed, a round, square orother form may be used with satisfactoryresults.

VHaving thus described` my invention, I claim: Y Y

The. combination in a dishwasher of vthe character describedof anozzle having a water' chamber .Y with a narrow. opening `at its outletend,v lthe walls ofA the nozzle converging on .the sides and ends ofsaid f chamber to said outlet, and the sides being a water-chamber witha narrow opening at its outletend, the walls of the` nozzle convergingon the sides and endsof saidV chamber to said outlet, and the sidesbeingslig-htly convex at the outlet inthe direction ofthe flow of'water..n
